Rojavon finished chapter 3. And since I havne't clicked on ship's hollow I get a screen showing "Interlude". I'm probably going to send him to Ilum (planet Josra skipped) since I already have Josra on Mekab (new hutt quests).

Apparently if you kill Rogun the Butcher you get the the title "Butcher’s Bane" but I didn't kill him so no title.

Nope, once its done, it's done. Just as well, presumably if you kill Rogun than you'd have to face the two sith by yourself. Not killing him he helps with the fight. Actually, I was kind of expecting him to turn on me once the sith were gone, but it didn't happen.

All bow before Xoanan, Dark Lord of the Sith. He finished chapter 1, gained the title Lord and some followers.

Click to reveal..

His companion Khem Val is currently possessed by the spirit of Zash, a female sith. Now Khem is really crazy, suffering from a split personality. All they have in common is they both want Xoanan dead, but can't hurt him because Khem Val is bound to his service by the Force.)
